User's Guide Fireface UFX © RME
At a sample rate of 48 kHz, up to 60 channels (inputs and outputs), at 96 kHz 34 channels, at
192 kHz 16 channels can be selected. The actual number of channels that can be used error-
free depends on the media, see chapter 36.5.
The playback from a storage device does not change the current sample rate. To match pitch
and speed, the sample rate has to be set manually to the correct value. Playback can be as-
signed to multiple outputs.
The UFX can play back externally recorded WAV files, as long as these have 16 or 24 bit reso-
lution.
The recording signal is taken before EQ and Dynamics, on both inputs and outputs. To record
with EQ/Dyn, activate REC on an output and route a signal processed by the input EQ/Dyn to
that output. The insert point of playback is at the same place.
The block diagram shows the signal flow for various situations, depending on the state of Loop-
back, EQ for Record and Play active. In the diagram Loopback and EQ are switched to off, but
a playback is active in the input.
Some extra notes that are worth to be pointed out again:
• The signal recorded by audio software is usually that from the input. But when the option
DSP – EQ for Record has been activated in the Settings dialog the software receives the
Play input signal – as soon as a playback is started from the USB device.
• On an output Echo/Reverb gets recorded. To add Echo/Reverb to a playback the playback
must be assigned to an input.
• A playback via USB can not be processed and immediately recorded again via DURec. Whi-
le the block diagram seems to present such functionality please remember that DURec can
do only one thing at a time – record or playback.
